Handle venomous aquatic pets carefully

In this column, I will discuss four possible venomous pets available for purchase for marine habitates.

The most popular is the group called Scorpaenidae fish. The lionfish is at the top for popularity. The scorpionfish and stonefish also are in this group.

Note: Hobbyists with allergies should use caution when owning venomous aquatics.

1. Scorpionfish do not aggressively attack, but the hobbyist may accidentally brush against a spine, receiving a dose of venom. Seek medical help.

2. Next is the lionfish, which may attack. They can deliver venom three ways -- from the dorsal spine, pelvic spine, anal spine.

These spines are hollow for venom to be delivered. The more pressure used, the deeper the penetration and the more venom delivered.

With this scenario, it is possible for a spine to break off deep in the skin and leave a fragment to become infected. The venom may cause a systemic infection if medical advice is not obtained promptly.

3. Stonefish usually do not show aggressive tendencies, yet they have venom with the potential to kill.

Being accidentally stung by this venomous fish has the potential to cause death even months later due to the amount and potency of the venom.

These fish have large venom sacs and very wide envenomating spines for fast delivery of huge amounts of venom, and shock or death may occur.

The victim needs to seek immediate medical help. The wound may take several months to heal. Always pay special attention to the daily care prescribed by the doctor to help prevent complications.

Another venomous aquatic pet is the stingray. Stingrays, who have a deadly tail spine, do not tolerate close swimming above them.

This may present a threat, triggering a defensive attack. Their long barbed tails swing into action, piercing the perceived attacker's skin and injecting venom.

Freshwater stingrays have more potent venom than saltwater stingrays, but either can cause death if the venom is delivered to a vital organ.

The hobbyist may encounter accidental stings from their pet rays, usually in the hands and arms, with pain peaking in two hours. Seek medical advice.
